Causes of Brick Deterioration
Brick walls are a beautiful and durable addition to any home or building. However, over time, bricks can deteriorate due to various factors. Extreme temperatures, freeze/thaw cycles, exposure to precipitation, or foundation shifts are common causes of brick deterioration. When bricks are exposed to these elements, they can develop cracks and wear down, leading to a weakened structure.
Types of Damage to Brick Walls
Damage to brick walls can vary in severity. It can range from cosmetic cracks to the deterioration of mortar joints and the bricks themselves. Cosmetic cracks are usually superficial and can easily be fixed. However, structural cracks can pose a serious problem and must be addressed promptly to prevent further damage to the structure.
Cosmetic cracks, although not structurally threatening, can still allow moisture to seep into the brick wall. Over time, this moisture infiltration can lead to water damage and compromise the integrity of the wall. Therefore, repairing cosmetic cracks is essential to prevent larger structural cracks from occurring in the future.
Another type of damage to brick walls is spalling. Spalling occurs when old mortar is replaced with new mortar that is harder than the original brick. This can cause the bricks to break down and flake off, resulting in a crumbling appearance.
Repairing Cracks in Brick Walls
When it comes to repairing cracks in brick walls, it is crucial to distinguish between cosmetic and structural cracks. Structural cracks are a cause for concern as they indicate serious structural damage and should be addressed by a professional. On the other hand, cosmetic cracks can be relatively easy to fix.
To repair cosmetic cracks, follow these steps:
- Clean and prep the damaged area: Remove any loose debris or old mortar using a stiff bristle brush or a grout saw.
- Mix and apply new mortar: Once the area is clean, mix fresh mortar and apply it to the crack using a pointing trowel or brick trowel.
- Remove excess mortar: Take care to remove any excess mortar and ensure a neat finish.
- Level the repaired area: Use a jointer brush to level the surface of the repaired area.
Remember to take safety precautions when working with masonry. These include wearing a mask to avoid inhalation of stone dust and using proper lifting techniques to prevent back problems caused by heavy bricks.
- Clean and prep the damaged area.
- Mix and apply new mortar.
- Remove excess mortar.
- Level the repaired area.
It’s important to distinguish between cosmetic and structural cracks. Structural cracks require professional attention, while cosmetic cracks can be repaired following the steps mentioned above.
The Process of Repairing Old Brick Walls
Repairing old brick walls is a more involved process than simply fixing cracks. To begin the repair process, cracked mortar needs to be removed and excess mortar must be scraped away. This can be done using a combination of tools including a cold chisel, wire brush, and engineer’s hammer.
Once the old mortar is removed, the area is sprayed with water to dampen it. This helps to improve the adhesion of the new mortar.
Next, new mortar is mixed following the appropriate ratio of sand, cement, and water. The mixture is applied to the sides and bottom of the opening where the old mortar was removed. Then, new bricks are inserted and tapped into place using a mallet. Excess mortar is removed and any voids are filled.
The repaired area is then sprayed with water periodically over three days to aid in the curing process.

Understanding Spalling in Brick Walls
Spalling is a specific type of damage that can occur in brick walls. It happens when new mortar, which is harder than the original brick, is used to replace old mortar. This mismatch can cause the bricks to break down and flake off, resulting in a spalling appearance.
Historic brick walls were built with softer bricks and lime mortar, while modern walls use harder bricks and Portland mortar mix.
To repair spalling, the damaged bricks need to be carefully removed and replaced. The old mortar is chipped away, and new mortar is applied to the sides and bottom of the opening. The new brick is then inserted and tapped into place. Excess mortar is removed, and any voids are filled.
It’s important to match the hardness of the replacement mortar to the original brick to avoid future spalling.
- Use new mortar that matches the hardness of the original brick
- Remove damaged bricks carefully
- Apply new mortar to the sides and bottom of the opening
- Insert and tap the new brick into place
- Remove excess mortar
- Fill any voids.
Importance of Repairing Cosmetic Cracks
Cosmetic cracks in brick walls may seem insignificant, but they can lead to more significant structural issues if left unaddressed. Moisture can penetrate through these cracks, causing water damage and compromising the integrity of the wall. Repairing cosmetic cracks is crucial to prevent the development of larger cracks in the future.
